' 13 claims. (o1. 299-78) The present invention relates to expansible hose reels of the type disclosed in United States Patent #2,010,811, issued August 13, 1935, to James A. Craig,for Expansible hose reels.

The herein device contemplates an improvement of a hose reel and its mountingtherefor, and wherein the reel is enclosed in a cabinet for protection against the'elements, when mounted in exposed positions.

A further feature is in the provision of means whereby the cabinet may be quickly opened and the reel quickly moved, exteriorly of the cabinet, to operative position, for speedy operation, in the emergency of the occurrence of a fire.

Another feature is the provision of a locking means to firmly lock the hose reel in its outer operative position, but which means is manually releasable, when the reel is to be returned to non-operative, protected position, Within the cabinet in which latter position it is also locked.

A further feature is in the provision of a rail guide, preferably wholly within the connes of the cabinet whereby to support the reel and its appurtenant hose in desired angular position of operation, thus to relieve the water connections and couplings of undue strains.

A further improvement is in the provision of a cushioning air chamber within, or associated with, the hub section of the reel, whereby to inhibit water hammer upon the rst rush of water therein and to evenly control the initial outiiow oi' water from the hose upon commencement of operation thereof.

A further feature is in the provision of improved means for permitting the automatic two way expansion of the reel, upon the distension of the collapsed hose thereon by the initial entrance of water pressure therein, when the water is admitted to the hose while still reeled upon the reel, thus enabling the water to reach the fire simultaneously with the approach oi the nozzle thereto. This feature is a great time saving element in the emergency of a fire occurrence.

Further features of structural advantages will be noted as the herein description proceeds and it is obvious that modifications may be made in the structure herein without departing from the spirit hereof or the scope of the appended claims.

In Figs. l and 2, the reel, generally denoted by R, is shownV as being mounted within an enclosing, four Walled cabinet C, which may be made of sheet metal and be suitably aixed to a wall W, Fig. 2.

The cabinet has one of its walls in the form of a door 2, hinged upon one of its Walls 6, Fig. 2, so as to drop downwardly, as shown dotted. A handle 3 near the upper edge of door '2, affords 'convenient means for manual manipulation of the door. The door may also be provided with snap catches along its upper edge, and these catches being well known, are not shown.

Within the cabinet interior is rmly located a pedestal water connection 5 5, its base 6 resting upon the iloor wall l and may be riveted An inlet water pipe I0, passes from the exterior of the cabinet to the interior thereof, Fig. 1, by means of a bore in side wall I, said pipe being coupled to a hand valve 8, said valve being in turn connected to the hollow interior of the pedestal 5, by a nipple 1.

In the 'top of the pedestal, as viewed in Figs. 1' and 2, is located a stuiiing box joint Il, I2, which is packed therein for rotative movement, and which is in turn, connected to a T connection I3. The upper end of the T connection is closed by a capped pipe lll the upper end of the capped pipe having rotatable connection with'` an adjustable screw pivot l5, which in turn is fixedvso ly held to the top wall of the cabinet by suitable fixed bearing means I6.

As thus described, the pedestal 5 8 is xed and the adjustable pivot is xedly mounted, and between these both is journalled the connection II-I3 and I4, for rotation, under water pressure within.

The T I3 is connected at its mid-portion to a radius pipe Il, the other end of which is threadedly connected to the thread inlet end I of the reel R, Fig. 5, by a coupling c, Fig. 1. All of the foregoing described connections from cabinet inlet I to reel inlet I are made in a water tight manner, and in some non-essential details, the mode of connection may be varied.

As thus described, however, the essential feature of the foregoing reel connection, is to permit the reel R, when the door 2 is opened and dropped, to be pulled out of the cabinet, instantly, to the external dotted position, as shown in Fig. 2, the pipe connection I1, acting as a radius arm, the pivot of the pedestal and the stuiiing box connection I2 acting as trunnions for the radial out-swing of the reel and hose.

A hand operated Water line controlling valve 8, Fig. 1, located adjacent thepedestal and controlled manually by its handle 9, is tted between the inlet pipe I0 and the pedestal portion 5, thus providing convenient means for instantly turning on the water pressure, when the reel is first pulled out for active operation.

Owing to the weight of the reel and its deflated, wound up hose and nozzle, the latter two not being shown, but are well known in this art, a supporting track has been provided, to care for the gravitational forces exerted by such weight and to relieve the rotatable pipe connections of these strains, and, to this end, two vertical uprights, 2| and 24, preferably of angle iron, are suitably aixed between the top and bottom walls of cabinet C, as in Figs. 1, 2 and 3. These uprights, as viewed in Fig. 3 are so positioned as to act as terminal posts for stopping the quarter, radial, swing of the reel at the ends of its operative and non-operative positions, within, and exteriorly to the cabinet.

Two angle iron quadrant rails, one bottom as at I 8, and one upper, as at 20 are rmly aixed at their ends to the uprights 2I24, best seen in Fig. 3, the center of the radii of the quadrant rails being centered in the vertical axis of the pedestal 5 6.

The `rails I9-2Il are so bent, that one of webs thereof, as at a and bi, Fig. 2, face each other ilatwise to form a dual track guide of comparatively wide face.

Between said rails I9 and 20 is located a flanged spool I8, the flanges of which span the webs of the tracking guides, thus to keep the spool upon the webs.

The spool I8 is rotatively mounted upon the radius pipe I 1, and as the reel is moved within the limits of the quadrant, it acts as a roller to reduce movement friction.

As in Figs. 1 to 3, and Fig. 9, the reel support is provided with a latch, generally denoted by L, Fig. 9, which is located on the web of upper quadrant rail 20, said latch being pivotally mounted, by its arm 25, to a pivot bearing block 26, which is firmly aii'ixed to said upper rail 29. The latch L is substantially anchor or T shaped, as viewed in Fig. 9, the arm 25 having a downwardly depending latch arm 29 having a hook extension 32 on its lower extremity, said arm 25 having also an upwardly extending curved handle extension 21, with a stop extension 3U near its conjunction With arm 25. The web of rail 20 is provided with a slot 3|, through which latch arm 29 extends. Stop extension 39 and hook extension 32 act to limit the drop and lift'of the latch L, when manually operating the same in the slot 3|.

In order to hold the latch arm L under downward tension, there is provided a flat, olset latch spring 28, one end of which is suitably aflixed to the web of quadrant arm 20,' adjacent and parallel to the latch arm 25, the other end of the spring being offset, Figs. 3 and 9 as at 36, to overlie the latch arm 25, and thus to hold the latch arm down rmly when subjected to pressure by the spool I8, when the reel R is at the dotted position of Fig. 2, with the spool caught behind latch L, as in Fig. 9. As thus described the reel R is caught and held in its outer operative position and is there held against the hose unreelinlg forces in the direction of either of the arrows in Fig. 9. The latch L is manually operated to latch lock or unlatch the reel by moving it by the curved handle extension 2'! about its pivot point.

As in Fig. 9, a rubber cushionblock 38 may be mounted between the quadrant rails Iii-29 on one face of upright 24, to absorb the shock of outswing of the reel at its outer terminal movement.

The reel R as previously noted, has a threaded, cylindrical inlet extension 33 which is threaded at I, Fig 5, to be coupled to the outer end of the radius pipe I1, by a suitable coupling means C.

The cylindrical inlet pipe 33, Fig. 5, is provided with two spaced apart central iianges 353-40. The pipe 33 extends inwardly beyond the flange 48 as at ll, and is open ended, the open end extending part way into a cushioning air chamber 42, in the end of a reel trunnion E, the end of said pipe, at 45, being plugged with a threaded plug 43 to close said air chamber end.

The cylindrical inlet pipe 33, between the flanges 39 and 49 is provided with a plurality of peripherally located Water outlet slots 44, Figs. 4 and 5, which open up into a surrounding chamber 46, this chamber opening up into a threaded water outlet 41, which connectably receives a hose coupling 49, Fig. 5, to which is attached the usual hose 5I), which, normally is rolled upon the reel in collapsed condition.

The cylindrical inlet pipe 33 rotatably supports a reel trunnion, generally denoted by E, which is provided with an exterior, anged reel-side seat 5I near one end thereof, adjacent the inlet end of pipe 33, Fig. 5, and upon this seat is ixedly located, or seated, a reel-side 54 by its anged hub 55. The reel side 54 may be affixed to its seat by suitable screws between the flange of reel trunnion E and one flange of the channel hub 55, such as is illustrated at e-e, Fig. 5.

The opposite exterior end of reel trunnion E is cylindrical and slidably supports thereon a cylindrical reel-seat slide 5l, which is provided with a flanged reel-seat E2, and into which latter is xedly mounted the channel shaped hub flange 58 of reel side 55, said reel side being held 'to said reel seat 52 by headed screws e-e.

The reel seat slide is slotted longitudinally as at 59, Fig 5, and a screw 60, threaded into trunnion E, in said slot, acts as a radial key to prevent rotation of said slide on said trunnion, but permits oi the sliding, outwardly of the reel side 5S to the position shown in dotted lines E I, Fig. 5, under exertion of hose water pressure.

As thus described, the reel sides 54-53 and trunnion E rotate as one piece upon the inlet pipe 33, and reel-side 56 can concurrently slide outwardly on trunnion E.

In order to permit the trunnion E to rotate without leakage and to hold the trunnion in operative position on pipe 33, the interior of trunnion is provided with an internal ange 62, which abuts one face of pipe flange 4i), these flanges acting as a locating stop for the relative operating positions of pipe 33 and trunnion E.

On the opposite end of trunnion E, adjacent the inlet end of pipe 33, is located a flanged, interiorly fitted, packing gland 6ft, which fits. loetween the inner cylindrical surface of trunnion E and the outer cylindrical surface of pipe 33, the

angled, inner end of said gland compressively holding a compressible ring packing against the side face of pipe flange 39, thus permitting of the rotation of the reel structure on the pipe 33, without leakage. Adjustment of packing compression is accomplished by tightening the headed adjusting screws f-f located between the hanged portion of .gland Gli and threaded into the adjacent end of trunnion E. Gland 64 rotates with trunnion E on pipe 33. The bearing fortrunnion E is formed by the cylindrical edges of flanges 39, 40, 62 and the gland 64.

The reaction thrust of the packing gland draws ange 62 in closer contact with flange QE.

The reel-sides 513-56, as in Fig. 4, are preferably of a cast metal, in one piece and in the form oi wheels, with an outer rim, 55, a plurality of radial spokes 59, all integrally connected to each other and their flanged hubs 5l or 52.

On the score of lightness and strength, the cross section of the rims, spokes and hubs are channel shaped, the rims having relatively thin felly walls 56, Fig. 4, with flanges Eil-58 inturned at right angles thereto, the spokes 54 and 55 having side faces 59, with flanged side walls 'Hi-1l. The flanges of the rims, spokes and hub of each reel are, naturally, all connected to each other to each form an integral, light and strong unitary reel structure.

On each spoke of each reel, there is operatively mounted a tubular guide l2, which is fitted between the opposite flanges 'l0 and il of each spoke, and held therein at the outer end thereof by a rivet 18, which engages between the side face 69 of each spoke and the outer flattened end l5 of each guide, Figs. 'l and 8, said iiattened end 'i5 having a hole 'E6 to receive said rivet.

The lower end of the guide l2 may be left open, to allow of the introduction therein, before riveting in position, of a coiled compression spring 71. The lower ends of the guides T2, when in operative position, as in Fig. 5, rest upon and are retained by the channel sections of the hubs 52 or 55. Thus when the inner open ends of the guides are seated and the outer ends 'i5 are riveted, the guides are firmly held in fixed operative position between said sections 52-55 and the lianges 5l-5|. The spokes of each reel-side are located, in assembly, to be radially registered with each other, in opposing radial alinement, as in Fig 5.

The guides l2, are each provided on their exposed faces, when in reel position, as in Fig. Il, with a longitudinal slot 13, the lower end of which, as viewed in Fig. 7, terminates in an enlarged bore or aperture i4.

The purpose of this slot and bore is to operatively receive and hold therein, in conjunction with the spring 1l, an expansible cross bar or strut, generally denoted by 19, and shown in enlarged section in Fig. 6, and shown also in reduced sectional Views, in operative position in Figs. 4 and 5.

As in Fig. 6, each cross strut 19 comprises a pair of telescopic tubes, the outer one Si! slidably receiving therein an inner tube 8l. Both tubes on their outer, exposed ends, are provided with plugs llt-S6, which are pinned in with pins 88-88, and are further provided with integral ball ends 811-84 which are held to the plug ends 86-86 by cylindrical necks 85-55, the diameters of which are approximately the same as the width of slot it of tubular guide 72, Fig. 7, so that said necks will be slidable within said slot.

The plugs 36--85 are each provided with lugs 83-83 which project interiorly of the tubes Sii-8l, and these lugs are each bored at their ends to receive therein the hooked ends of a coiled tension spring 82, Fig. 6, an-d thus the telescopic tubes are always constrained into normally non-expanded position.

The cross struts 19, as above described are assembled to the reel R, as in Figs. 4 and 5, by having their ball ends {i4-84 introduced into the apertures 'Hl of a pair of the tubular, slotted guides 12, after which the spring 'll is introduced, thus pushing the cross struts 1S, to the upper part of the slot 73 of the guides l2, as viewed in Figs. '7 and 5. This cross strut assembly may be accomplished after the opposed registering guides 'l2 have been riveted to the reel-sides, but before the reel-sides have been assembled to their rev spective hub seats.

After the assembly of the reel structure as above described, the hose 50 is connected by a coupling i9 to the threaded end 41 of the reel nozzle, Fig. 5, and with its appurtenant nozzle, not shown, is wound, in a collapsed condition, around upon the cross struts 19, as partially indicated in Fig. 5, and the reel is then connected by its inlet pipe 33, to a source of water supply connection I), by a coupling C, Fig. 1, and is thus in condition when housed as in Fig. l, with the valve 8 closed, to be operated quickly in the event of a fire occurrence.

It takes but little time, to open the door 2,

pull out the reel R to the operative position shown dotted, in Fig. 2, pull the valve 8 open and grasping the nozzle, run tc the origin of the re. As the nozzle is taken to the re water commences to issue from the hose and reaches its full force upon reaching the lire..

The hose as it is withdrawn from the reel is lled to its full capacity with water and this slidably expands the reel side 55 to position lil, Fig.

5, and contracts or inwardly cprnpresses the cross struts 'i9 to dotted positions 98E-9G and thus, while the nozzle is being carried to the fire point, the hose is expanded to its full capacity and the water issues at full pressure and volume from the nozzle before and by the time the nozzle has reached its operative position.

This device may be operated, successfully, between any intermediate points of the entire length of the hose, and is completely operative as soon as the hose. is filled with water.

From the foregoing, it is obvious that considerable time is saved in the operation and twoway expansive action of the reel, as herein disclosed.

The purpose of the cushioning air chamber 52, as shown in Fig. 5, is to take up the shock of the first impact of the incoming water into the reel when the valve 8 is irst opened, to relieve the initial water hammer efect of high water pressure upon the hose, and to smooth the resultant stream of water as it leaves the nozzle.

A primary cushion chamber is also provided in advance of the cushioning chamber 42, and this air chamber is formed in the pivotal upright pivot connection i4, Fig. 1, the latter being connected to the T union I5. As the tubular pivot member is of pipe form, capped by a water-tight pivot capp, the air in this upper sealed chamber takes the rst full force of the water pressure, coming from source Hi, and acts to break the hydraulic impact, before the water reaches the reel and its cushion chamber 42.

Upon occasion to return the reel to its housing, or cabinet, after use, after the hose has been emptied, dried and re-reeled, the reel is then swung inwardly into the cabinet, where the roller i3, on the radius arm Il, comes into contact with the spherically conformed cam blade J, Figs. and l1, of the spring latch Si, which is held to the under side of guide rail quadrant I9, by a screw fastening g'.

The head of the cam J projects upwardly through a slot j which is cut into the rail tracking web b.

When the reel is moved into or out of its interior non-operative terminal position, it cams the spring latch downwardly as shown dotted in Fig. 10. A shock absorbing bumper cushion 38, Fig. l0, performs the same function as that described for the cushion 38 of Fig. 9.
